We ship almost all of our orders through US Postal Service.
For large items over a certain weight/size threshold, we will ship UPS. This is rare and we will notify you ahead of time.
The United States Postal Service offers delivery service or a comparable alternative for all locations in the US. UPS and FedEx don't provide delivery certain areas, especially rural routes with low population density, and they will actually work with the Postal Service to deliver items addressed to these areas that they do not service. From the USPS website:
"The Postal Service is the only organization in the country that has the resources, network infrastructure and logistical capability to regularly deliver to every residential and business address in the nation."
